Q: thanks for those tips i was actually thinking i would run it with mobil1 15w50 & see if that helped it any. i may try putting a lower temp thermostat in it though it currently runs a notch above center. ive never owned anything with this engine in it before so i dont have a good feel for what normal. my prior a beloved 80 short bed with a 225 slant 6 & 4 speed od stick shift usually ran a bit cooler. joe joe exotic-scales wrote i bought an 89 dodge b250 van with the 5.9 l gasoline engine throttle body fuel injection. its got 123k on it. the vehicle drives and sounds great starts right up even after sitting doesnt use any oil -- only problem was that after driving it a while the oil pressure would drip way down and the van would stall. so i replaced the oil pressure sender then the oil pump. no change. i even installed a good mechanical oil pressure gauge. when i first start it and the viscosity is high its right up around 60 psi. after im driving for 15 minutes or so its down to 40. if i come to a stop at that point it will drop to 20. drive it a bit longer and come to a stop and it falls right down to zero. at this point
